Going over one method of engraving a 2D design with a CNC. This is my third video as I learn to use my Shapeoko 2 DIY CNC from Inventables.

I ordered my Shapeoko 2 and it should be arriving at the end of February. I can't wait to get started using it. Have you found any information that details how to modify the Shapeoko 2 to have a larger work area to be able to accept 2' x 4'? I know that the current configuration is about 12" x 12".

It's really just a matter of buying the materials. You're going to need longer:

MakerSlide
80-20 aluminum extrusion
MDF wasteboard
GT2 Belt

Probably some extra M5 fasteners too. All of this stuff is available on the Inventables page, but you're understandably going to be upping your costs.

And you're probably going to have to make some kind of cross/reinforcing frame for the wasteboard, since you're going to need to tile multiple pieces of MDF to span the work area.

Get some 1 meter length of makerslide for the 2' span, and 1.8m MS for the 4' span. Only thing to check is rigidity, I'd put the longer span on the fixed Y-axis, so you can reinforce it from the outside where the gantry won't run into anything.

Thank you for the reply. I will look at the inventables.com website and see what they have. I have seen larger versions of the machine, however they do not go into detail about the modifications that were made . Your info is a good start.

I have another video outlining the assembly process you can take a look at (if you haven't already). There really isn't much difference from the assembly of the Stock Shapeoko. The operations you perform are the same: tap the ends of the makerslide, bolt them to the end-plates, mount carriage assembly on rails, affix the belts.

It's only the wasteboard that you have to find a creative way of attaching.

Oh, and also, for a machine of that size, you'll have to also take into account how much slack in the cables you'll need.

Thanks for posting great job!
